AtD isn't compatible with TinyMCE v4

Add in a conditional that disables it if TinyMCE version is 4.x or
higher.
This is a temporary fix until we rework AtD to behave properly in v4.x
See #38
Move the `lib` directory.

Move the `lib` directory for `jetpack_require_lib()` into the `_inc`
directory, so that all included libraries are now two directories down
and won’t be seen as plugins when deleting Jetpack.
Fixes #39
Create a .svnignore file

This file will tell SVN which files to ignore when deploying to the
.org repository.
`svn propset svn:ignore -F .svnignore .`
